
Problem

◦
Lack of standardisation mechanisms, that
enable state
-
of
-
the
-
art
of medical educational resources
to be discovered, retrieved,
shared and re
-
used across European Academic Institutions


MedBiquitous Annual Conference 2011


Solution

◦
Standardised format of description of the resources by means of metadata

◦
Metadata need to be described by state
-
of
-
the
-
art e
-
learning standards
and make use of their many advantages


Semantic Web, Linked Data






Aim

◦
To improve medical & healthcare education


Need to be widely used (interoperable)


Reusing existing e


Should not reinvent the wheel


Extending e


Standardisation format in order to enable
sharing and retrieving of resources is essential


Choice of the right format (RDF/XML) will link
the data of the Web. Benefits:

◦

Access existing knowledge

◦

Interoperability between resources


Shift towards an Ontology

Aim:

To enable specialized state
-
of
-
the
-
art medical
educational content of varying types to be
discovered, retrieved, shared and re
-
used across
European higher academic institutions.

How:

By implementing and evaluating two different
solutions

•

A “mashup” platform that aggregates content published in
isolated Learning Content Management Systems (LCMS)

•

A federated architecture of LCMSs based on Semantic Web
Services for search, interchange and delivery of learning objects
